1. When doing a pressure test on a water pipe, the first thing to pay attention to is the time issue, which needs to be carried out 24 hours after the installation, so as to ensure the safety and accuracy of the pressure measurement of the pipeline. If the time is not arranged well, it will affect the accuracy of the test structure.
2. When the pressure test is performed on the pipeline, the quality of the water meter is very critical, and inferior quality cannot be used. Because if the pressing speed is too fast, the cover of the water meter may be damaged.
3. Before the pressure test of the water pipe, the air in the pipe must be drained, otherwise the accuracy of the pressure test will be affected.
